Reinhardt's eyes widened, and he directly turned into a problem baby: "Why can the two wheels be balanced? Why don't they fall?"

"Turn the front wheel to change direction, why doesn't it fall?"

"Why doesn't it fall?"

The fact that two wheels can maintain balance is a game-changer for him.

It was too troublesome to explain this, and Luo Qiu ignored him.

After looking at it for a while, Reinhardt asked again, "The wheels are hard, why is the frame so stable?"

Speaking of this, Luo Qiu was a little proud: "Please look at the muscle suspension system I invented." ”

The structure of the bike is simple and the range of adaptation is wide, and the off-road bike can be ridden even if there is no road, let alone an extreme sports bike.

But Luo Qiu has not recovered, that is, he is stuck in the suspension, and without pneumatic tires, the skeleton of the bicycle is alive and well.

Pneumatic tires need to find rubber trees and a series of chemical treatments, Luo Qiu doesn't have this technology, he doesn't even know what plasticization means.

Until the advent of flesh and blood, the muscle suspension system was possible, the inner ring of the tire is dozens of high-strength muscle fibers, cultivated by Margaret, and then toughened, strong elasticity, and very high strength, suspended between the wheel and the axle, the shock resistance is higher than that of pneumatic tires.

"Let me try, let me try. Luo Qiu rode around, and was driven down by Reinhardt.

However, it is not easy for a person who has seen a bicycle for the first time to learn it, and Reinhardt has just ridden it and has been wrestling non-stop, so that he has to use his magic to support himself.

With the support of magic, he rode repeatedly for more than ten laps, and finally mastered the skill of balance: "You must keep both wheels in a straight line, and when you turn, you must apply a reaction force in the other direction to keep your balance all the time." ”

"Your Majesty, this bicycle is amazing, it is simply a genius invention. Reinhardt was extremely excited: "With a bicycle like this, the average person can maneuver as fast as a horse." ”

Luo Qiu smiled and shook his head: "No, it's much faster than horses, ordinary war horses have to rest after running more than ten kilometers, and the bicycle can be ridden for seven or eight hours casually, but the impact is inferior." ”

War horses are not only vehicles, but also combat effectiveness, and cavalry charging often has a decisive force on the battlefield.

Bicycles are just simple vehicles, but since the appearance of bicycles, with hot weapons, war horses have quickly withdrawn from the stage of war. Since then, the dragoons have become a class of troops who ride bicycles and carry rifles.

After figuring out the principle of the bicycle, Reinhardt muttered: "A skeleton is only less than forty pounds, the load does not need to be too large, one hundred pounds is just right, it really doesn't need steel, use wood?"

It seems that only wood can be economical and abundant, but Luo Qiu doesn't want to use it, because it is difficult to process, and his people are all skeletons, not carpenters, so they can't process wooden frames at all.

He wanted to find a material that was less difficult to process.

"Less difficult material?" Reinhardt frowned.

This involved the knowledge of industrial design, and Luo Qiu summoned Carter again.

"It's fun, haha, I love this kind of car. Carter's balance was better than Reinhardt's, and he learned it after two laps, but Reinhardt felt it was because he was holding on to the back.

"To reduce the difficulty of processing, you can use molds, frame molds, wheel molds, by the way, Your Majesty, Rox has invented a new plant activation solution that can accelerate the growth of plants. Why don't we use rattan for the frame and wheel?" Carter suggested.

Can soft rattan be used as a wheel frame?

Of course, Carter didn't say it casually, she found a mold of steel bent into a rudimentary mold, found a very common vine, stuck it on the mold, planted it, and buckled the two ends of the fracture together, and let Locke take the plant activation liquid and pour it into the mold, soaking the vine.

The vines soaked in the activation solution grew rapidly, and after twenty minutes, the entire mold was covered, and the positions of the fractures actually grew together, and the existence of the fractures could no longer be seen.

This is not the end, the fresh vine wheel is taken out, covered with polysoil, and after twenty minutes it dries like a ten-year-old vine, and when it is pressed hard, the rattan wheel is pressed and deformed, but as soon as it is let go, it springs back to its original state.

Hang the muscles to hang the spokes, so that even if you press hard, they will not deform, but will be full of elasticity.

Then apply defensive paint to the outer ring to increase its wear resistance, and a magic rattan wheel is complete.

The same is true for the frame, only the parts that are easy to break are reinforced with steel sheets, and then an iron fork is fine.

The various parts were assembled, and a rattan bicycle was unveiled like nothing before.

Luo Qiu was at a loss all the way, and he couldn't believe that rattan could really make frames and wheels until the last moment, but when he saw the wrist-thick rattan, he suddenly found that this material was really far more suitable than wood, light and hard, and the only drawback was that it was not easy to process.

However, with the combination of plant activation solution and polysoil, its disadvantages are no longer shortcomings.

Although the load bearing is not as large as that of an iron bicycle, it is no problem to carry a skeleton, and according to Carter's processing method, the frame, wheels and handlebars can be completed with skeletons, but when assembling, more intelligent workers are required.

As for vines, they are more common, they are all over the mountains, this plant has tenacious vitality, it can grow when planted, and the larger the amount of water, the faster it grows, and it is indeed a material that can be planted on a large scale.

Well, the rattan bicycle was finalized and sent down for production.

After the finalization work was completed, Luo Qiu's iron car was also snatched away, and Luo Qiu had nothing to play with.

Just then, Mobuck floated over: "Your Majesty, Hopeless asks to see you." ”

Hopless was let back, and when he returned to the principality, he became a hero to mankind, it was he who dissuaded the King of Steelbones from stopping, and it was he who saved all mankind.

From the strength shown by the Steel Bone Collar, if it weren't for Hopless's desperate communication with the King of Steel Bones, then the Steel Bone Collar would definitely have the ability to flatten the entire human world.

Hopless boasted like this, and Luo Qiu did not deny it, so he was made a hero of the human world, but at this moment, this hero of the human world's prestige was humbly kneeling in front of Luo Qiu, and said nervously: "Your Majesty, I brought all the undead creatures that can be found within the principality, but ...... It's just that...... Most of them are disabled. ”

"Huh, crippled?!" Luo Qiu frowned, and his tone became a little heavier.
